When you encounter a problem, the first thing to do is to see if it is
already known. See section Known Causes of Trouble with GNU CC. If it isn't known, then you should
report the problem.

Reporting a bug may help you by bringing a solution to your problem, or
it may not. (If it does not, look in the service directory; see
section How To Get Help with GNU CC.) In any case, the principal function of a bug report is
to help the entire community by making the next version of GNU CC work
better. Bug reports are your contribution to the maintenance of GNU CC.

Since the maintainers are very overloaded, we cannot respond to every
bug report. However, if the bug has not been fixed, we are likely to
send you a patch and ask you to tell us whether it works.

In order for a bug report to serve its purpose, you must include the
information that makes for fixing the bug.
